The good guy – who turns out be an Afghan immigrant himself -disarms the murdering terrorist, then lets him go? And then the one he let go rearmed himself and continued on?

Then- near the end of the video – an armed ‘someone’ good guy in the background behind them, has the shooters covered and he doesn’t engage either?

I’m sorry, I have no empathy and v-e-r-y little sympathy for the Australians.
